What is centripetal acceleration? SI Units? What is tangential velocity? SI Units? How do centripetal acceleration and tangential velocity relate to each other? Explain how you could increase the tangential velocity of an object? The centripetal acceleration? If a mass is 1.5 m from the axis of rotation and makes one revolution in 10 seconds, what is its speed in m/s? If m = 0.1 kg and the values above still hold, what is the numerical value of the centripetal acceleration?
